I am following this tutorial on creating a top-down car using Box2D:
Link: Two ways to make Box2D cars

Everything is fine until I reach the killOrthogonalVelocity function, line 152.
This code uses b2XForm which is not available in the current version of Box2D.

What is the equivalent of it in v2.1a? Or the work around is there isn’t?

Thanks in advance for your help.
